SPECIFICATION forming part of Letters Patent No. 410,560, datedSeptember 3, 1889. Application filed May 23, 1889. Serial No. 311,836.(No model.) 7

To (all whom it may concern:

Be it known that I, CHARLES PARTINGTON, a citizen of the United States,and a resident of Cincinnati, in the county of Hamilton and State ofOhio, have invented certain new and useful Improvements in CombinedCrossing and Switch, of which the following is a specification.

The object of my invention is to provide operating two sets of switchessimultaneously. They are arranged between the frogs of the crossing, sothat the switches connect one main line to another on the crossing,forming a combination crossover or slip-switch. One difficulty inoperating the mechanism has been to employ one switch-stand to move bothsets of rails easily, the friction of the parts, as well as the strainsof the moving rails, ina-kingit difficult to operate the rails. It isalso desirable to move the rails positively and to avoid lost motion,which is apt to occur when cranks or rods are used by turning the rodsdue to the torsional strain. My invention overcomes this difficulty,because the rods are moved longitudinally, and hence avoid the strainsupon the rods, which causes lost motion.

By employing the system of leverageherein shown and described I amenabled to move the switches with much less power employed than otherdevices heretofore employed for similar purpose, all of which will befully set forth in the description of the accompanying drawings, makinga part of this specification, in which Figure 1 is a top plan View of myimprovement. Fig. 2 is an enlarged broken section of the same, showingthe switch-rails closed. Fig. 3 is a broken sectional elevation of theparallel moving rods. Fig. 4. is an elevation of thejournal-boX-supporting rods. Fig. 5 is a sectional elevation showing theconnection of the switch-bars to the parallel moving rods.

A A represent one set of the main trackrails. B 15 represent anothermain line crossing the former one. C C represent the two endcrossing-frogs, and D D the central crossing-frogs E .E represent theinner switch-rails at one end of the crossing, and F F the innerswitch-rails at the other end of the crossing. G G represent the outsideswitch-rails at one end of the crossing, and II II the outsideswitch-rails at the opposite end of the crossing.

In operation the switch-rails E E and F F are moved simultaneouslyinward or out ward. Switch-rail E is connected by a tiebar 1 to theswitch-rail G, so that said rails move simultaneously out or in, as thecase may be, and switch E is connected by a bar 2 to the switch-rail G,so as to move it out or in simultaneously with the movement of the saidrail E. On the opposite end the switchrail 1 is connected by bar 3 tothe switch H, and the switch-rail F is connected by a bar 4 to theswitch-rail H, so that said outer rails are moved simultaneously by themovements of the inner rails.

The simultaneous movement of the switches is accomplished by means ofduplex parallel moving rods preferably placed one above the other, eachoperated by a reciprocating bar 5 6' of the switch-stand 7, said barsbeing operated by pins journaled in the groove 8 of the switch-standdrum 9. The bars 5 6 are connected to switch-bars 10 and 11, as shown inelevation in Fig. 5. The upper bar 10 is journaled to links a a, whichlinks are journaled to links I) b, the latter moving on the center 12,to which they are journaled. The center 13, which journals the link a to12, projects down through a slot in the upper parallel rod 16. Center 12is journaled to the under switch-bar 11, and the center 15 is hinged tothe under parallel rod 14:.

The duplex switch-bars operate duplex links, each of which operates oneof the duplex rods running at right angles to the plane of theswitch-bar, the object being to do onehalf of the work with the upperrod and the remaining one-half with the lower rod, both workingsimultaneously in unison, which compounds the leverage and enables theswitches to be operated with far more case and facility than is possiblewith a single rod. Thus the links a b operate the upper rod 16, and thelinks a b are hinged to and operate the lower rod 1%, so that whenstrain is applied, say, to open the switches, the said links a a b b aredrawn to the position shown by the dotted lines in Fig. 2.

The slot 17 in the upper rod is to allow the journal 13, which isoperated by the lower rod, to move freely through the upper rod, and thelower rod has a similar slot for the center 15 to move in likewise. Theswitchbar 11 is similarly slotted to allow the center d, which hingesthe links a, a. together, to move in said slot without affecting theoperation. The bars 10 and 11 travel simultaneously in oppositedirections, the lower switch-bar 11 operating on links I) b, and theupper switch-bar 10 operating on links a a. Hence whenever theswitch-stand is turned it brings those links into position shown in fulllines, Fig. 2, or in position shown in dotted lines, as the case may be.

The switch-rails are connected at their ends to the duplex parallel rods14 and 16 by duplex links, which have the same movement as those formingthe central connections of the switch-rods. Thus the switch-railE' ishinged to links 18 and 19 by the center 20. Link 19 is hinged to link 21by center 22, which moves in the slot 23 of the upper parallel rod. Theswitch-rail E is hinged to links 21 and 24 by the center 25, and links18 and 24 are hinged together by center 26, to which the upper parallelrod 16 is hinged, and this rod is provided with a slot 23, so that thecenter 22, to

which the lower parallel rod is hinged, will pass freely in the saidslot and allow thelower rod to operate the links 19 and 21. The duplexrods 14 and 16 are thus moved in opposite directions by the centercompound link movement, each operating to move the switchrails inward oroutward, as the case may be, one operating on the links 18 and 24, andthe other on links 19 and 21, the two traveling in opposite directions;and the center 22 traveling in slot 23 toward the center, as the rod 16travels from the center, necessitates the slot 23to be twice as long asthe distance to which the slot-rail moves, which, say, is five inches.

The rods 14 and 16 are suitably guided in guides,which are preferably ofthe form shown in Fig. 4, which are placed at suitable distances apartand secured to the ties, as indicated by letter I, Fig. 1.

The ends of the duplex moving bars and switch-rail connections are eachthe counterpart of the other.

27 represents a lever rotating the switch drum 9 and moving theswitch-bars 10 and 11. These bars travel in opposite directions and openor close thelinks a a b b, as the case may be, which in turn drive theparallel rods and move the end link mechanism and draw the switch-railsinward or outward, as desired.

It is obvious that the parallel switch-bars 10 and 11 can be operated byother mechanism than the double-acting stand here shown; but this I deemthe best.

It is also obvious that the duplex rods 14 and 16 can be used to movethe switch-rails at one end of the crossing only.

Having described my invention, what I claim is 1. A combinationcross-over or slip-switch device, combined with and operated by duplexhorizontally-moving rods actuating duplex-jointed links, substantiallyas specified.

2. In combination with the duplex rods 14 and 16, having connection withswitch-rails and operated by a switch-stand, the central duplex links aa b b, hinged to each other and to the duplex rods and switch-bars,substantially as herein described.

3. In combination, the duplex rods 14 and 16, hinged, respectively, toopposing duplex links, which duplex links are hinged to theswitch-rails, whereby the said rails are moved toward or from each otheras the duplex rods are moved, substantially as herein set forth.

4. In combination, the duplex rods 14 and 16, respectively hinged toopposing duplex links at their center and at either end of the crossing,the latter links being hinged to their respective switch-rails, wherebythe moving of the duplex rods simultaneously moves the switch-rails ofthe crossing, substantially as specified.

5. The combination of the double-acting switch-stand, the duplexswitch-bars 10 and 11, and the duplex central links hinged to said barsand conversely hinged to duplex rods 14 and 16, which are connected withthe switch-rails, substantially as specified.

6. The combination of the parallel duplex rods 14 and 16, each providedwith slots 23 and 17, and hinged to duplex links at the two ends and tothe central duplex links operated by the switch-bars, substantially asspecified.

In testimony whereof I have hereunto set my hand.

CHARLES PARTINGTON.
